Entrance pupil mask (left) and LS mask (right) for the Roman HLC configuration on THD2. The mask sizes have been scaled to the respective optical sizes on THD2, in particular to the 8.3 mm clear pupil on the in-pupil DM2. The LS diameter of 6.648 mm is 80% of the pupil mask diameter. The strut width of the pupil mask and LS is 0.28 mm in both cases. The large central obscuration and nonradially symmetric supports are particularly challenging for coronagraphy.
